Starring Charlie Day, Rob McElhenney, Glenn Howerton, Kaitlin Olson and Danny DeVito, the black comedy follows a bunch of "depraved underachievers" as they attempt to run Paddy's Pub in Philadelphia.

'The Gang' and their constant schemings – and failed attempts – at trying to get ahead usually land them in a world of hurt, but hey, you have to pay the troll toll.

It's Always Sunny – which up until now had only been available in the UK on Netflix – was recently renewed by FX for a further two seasons, tying it with The Adventures of Ozzie and Harriet as the longest-running live-action sitcom in US TV history.
